Small oil leak, RHS cover, bottom rear bolt

[earemike]

Hi again,

Pulled the lower rear bolt from the rhs cover and noticed it was covered in a silicone like substance. Given this bolt is where oil was gathering (& spraying my boot) I was keen to know if oil creeps up the threads & what to do next to find the leak source. If I'm lucky it's anaerobic gasket maker & I'm done, otherwise what should I check next?

Could be leakage at the gasket, but it could also come from the oil seal behind ignition plate.

Thanks Tom,

I?ll try and search ignition oil seal & see what I can find.

Remove the alternator cover.
If it's slathered in oil, as is the alternator, then the crank oil seal has gone.
It can be picked out and replaced with the inner cover in situ but easier to remove the inner cover while you are that deep into it.

Thanks Grant,

The gold housing & cover are dry - so perhaps just that gasket?

Sometimes, especially if bike has been in an accident or alt cover has been grounded heavily, the inner cover can bow outwards between the two rear bolts where the cover goes to only its single thickness causing a slight oil weep. Careful inspection may find a small crack there also - cover can be "manipulated" straight and crack can be repaired by (preferably) weld - but have seen araldite or similar do the job. - have done plenty over the years - regards - Phil
